,To all whom it may concern: l

Be it known'that l, Josnrn van' Acumen, a' citizen of the llnited States.' residing .in

Pittsburgh, in the county of Allegheny and 'Y y 5 State of-Pennsylvania, have invented a neivthel hyprodu'cttype. It Willy be understood.

and useful Improvement in Cooling Means' for Exhaust Mains, of which the following '1 .is a specification.

" This -'nvention relates in general to smoke or exhaust mains, such'.forexainple, ,as are:

utilized in colging plants for carrying` off the smoke incidental tothe charging operationv of a heated coking oven or chamber. -An essential object of the invention' fis thel pro vision of an'exceedingly simple', economical' and eicient means for cooling both the outer Wall and the inside and bottoni 'of the main, thereby preventing overheating' of thev main by the hot smoke or other exhaust products passing' therethrough and possible explosions caused -hy combustible products enterln the drawings :i

ing and mixing main. 1 i t With the ahovev and Iother objects in View.

vwith air in an overheated -25 lthe invention consists in certain novel *asrangenients, constructions, and combina-- tions of parts hereinafter described `in a preferred form and particularly set forth in the claims at the end of the specification.

In the 4illustratoril embodiment of the invention, the cooling,r means is utilized in eonnection `with a. smoke main for a eoking' plantor battery, said main being employed for the purpose of carrying' oil the smoke in-l cidental to the operation of chargingr an oven or coking. chamber oi said battery. ForY c'onvenience,the present description" o'l' 4,'thecooling means will beconfined to this usegof thc invention; features ot' construchodiinentherein described.

I i Referring tov the' drawings, there ind'i .cated at l1 a'frag'inentarysectiontaken lone'-l gitugli-nally .l through 'an oven or; cokngpA i Qhaniherofla coke oven battery or pla-noot f coking ,chambers arrange'dside by side and having t'heusu'al alternating heating chambers or flame'fiues intermediate adjacent `poking' chambers'. kEach colringfchamber or oven is provided Wit-h a set ofgchargin'g holes l2 and. also, in the present' instance,vwith a usualconstruetion, einbodyinga plurality of".

smoke outlet` 13 independent of the charging I holes.l The charging holes 12 and the smoke' outlet 13 extend through the top-14 of the" @cking chamber or oven and are each ,pro-

4 vided with the usual suitable closures, not. shown, for closing the top of theoven during the -coking operatiom-but whichmay be removed -during the charging; operation. For charging an oven or cokingchamber,

there is usually provided a 1or1ry-c`ar,indi 4 cated by dotted lines atv 16 inJ Figure l1,;and

adapted to runnen tracks 17v extending. lengthwise` across the top of' the'oi7'en battory. Thelorry-car isprovided with a plurality 'of coal hoppers 18, havin depending municating' with an independent gas outlet spouts 1,9, the latter being ada ted tolcominunicate with the set of charging holes 129i .95

21 in the top'of each v-coking chamber or oven, and from such ascension pipes the evolved gases are dra-Wn through a collecting main 22, through whichhey pass'to the byproductrecovcry appara us. i

ilu the present instance, the invention is applied in connection. with a. smoke Inail;-

adapted to be connected Witha'n independ` ont smoke outlet 13 by means of a traveling smoke-Hue carriage, 'such .as vis disclosed Vin the cti-pending application of Joseph Becker, Serial' No. 264,967, "filed December 2, 1918. This smoke-flue carriage forms no part of the present-invention, and itV will be. sutlieient for present purposes to describe briefly the c'mstructionl and operation of the carriage, as follows: The carriage 23runs on tracks 24 erctending lengthwise of the oven battery and supported thereabove in a trarne 110 25; said carriage 23 is provided with vertimwthrough an inlet in Athe at bottoni ot the smoke main 29, carrying with it the bottom closure plate 3() and concurrently the lower 5 pipe section 26- is lowered down ojver thesmoke'outlet 13 of an oven or chamber, thereby forming a connection -tor permitting the smoke evolved during the charging operation of such chamber topass from the latter intothe smoke main. Normallyl the bottom closure plate rests on a seat 37 formed by an annular vertical flange pro-.

jecting upwardly from the bottom of the main. i5 The smoke main 2S) extends longitudinally, preferably clear across the top of the coke-oven battery and, in the present instance, may be provided with a curved top and a flat bottom. The present invention is `0 particularly concerned with the provision of an exceedingly simple, economical and etl'icient means-for coolinr 4the outer Wall and the interior of the smokepmain 29, thereby preventingoverheating ot and pos 5 `sible explosions 'within said main by the heat Icontaining smoke combustible products, and flame which enter the. main in Alarge quanti ties... These products are not only liable to cause buckling of the main whenever a, l charge ofcoal is introduced into one ot the superheated coking chambers or outlets, but as they contain combustible matter, including coaldust in large quantities explosions are likely to occur Within the main. it il' is i allowed to become overheated and the combustible products are allowed to mix with the air in the main. ln its present en1bodiment, the cooling means conveniently conf sists `oli a water pipe 3l. extending substan- ,tiallyy all the way along the sn'ioke main 2f). This-water pipe is furnished with a coin tinuous supply ot' cooling' water and is pret'- erably supported. in a. 'position centrally above the curved top of the smoke main 29. Formed in the'bottom otisaid pipe 31 is a series'of ,discharging holes 32 which permits the Waterironi the pipe 3,1 to discharge onto the curved top ot' the smoke main and flow 'substantially equally down the opposite 4sides of 'the'y latter, thereby maintaining a. continuous ilow'of cooling` water over the Wall of the smoke main and eifectually preventing overheating. v-'lhe discharged Water is collected in gutters, or troughs, 33, respectively located onv opposite sides of the smoke main and` preferably yco-extensive therewith. These gutters 33 may be formed of angle bars 34 mounted on laterally eX- tcnding portions S5-of the flat bottom of' the main. From the .gutters 33, the Water flowsthrough holes 38 in the opposite sides of the main and 'entering the main floods the bottoni, keeping the interlor cool. By reason of thesaldfianges 37 the water withinithe.

main is kept from flowing into the pipe of the smoke-flue carriage. In practice, how-r ever, it will be found convenient to keep the wat-'er within the main/at a constant level, by 'providing1r a damof any Vpreferred form at one end of the main. As the main is constantly flooded with cooling Wateigany coal dust carried by the discharging'smoke is precipitated in thewater, andthe danger of explosion is to a great extent eliminated.

It' ldesired the main. may be provided. with an inspection holeadapted to bel closed by a suitablepivoted cover 36.` Y y y Y The invention as hereinabove set forth is embodied in a particular forin of construction but may be variously embodied Within the scope of the claims hereinafter made.
